Troubleshooting with the T1 ToneMatch Audio Engine Parametric EQ
Using Para EQ to solve a problem frequency
In this example a Bassist was having a problem with a resonant note (B flat).
Chuck-at-Bose provided this approach.
Hilmar-at-Bose had a different approach
Here is one method to eliminate a boomy note
a) set the level of the para EQ to a cut, say -10 dB
b) set the width to fairly narrow, say .25 octaves
c) start with a rough estimate of the offending frequency and then move the frequency around until the offending note gets tamed best
d) you can press on the level control to toggle between on and off which gives you a direct A/B so you can judge the effect better
Once you have centered on the frequency you adjust the level and width to taste.
Estimating the frequency:
- Low octave of the bass is from 40 Hz to 80 Hz (E1 to E2), A1 is at 55 Hz
- Low octave on the guitar is from 80 Hz to 160 Hz (E2 to E3), A2 is at 110 Hz
- 2nd octave on the guitar is from 160 Hz to 320 Hz (E3 to E4), A3 is at 220 Hz
